As of now, it is practically difficult to think about an existence where PC networks don't exist, since throughout the long term they have gotten significant for everything to work as it ought to, from medical clinics and retail outlets, to the most extraordinary of the networks: Internet.

From the start, PC networks were utilized in a set number of uses, the majority of them military or logical, yet their utilization has extended from this area to the workplace, industry and the home, bringing about the making of different kinds of networks, each adjusted to the particular necessities of the climate.

In this post we will discover data and qualities about the fundamental kinds of networks that we access in our every day work, maybe even without acknowledging it.

Most normal sorts of networks

- LAN (Local Area Network)

The Local Area Network (LAN), or by its interpretation into Spanish Local Area Networks, are the most far and wide kind of network, being utilized principally for the trading of information and assets between PCs situated in a moderately little space, like a structure or gathering of them, like instructive or government establishments and surprisingly in our own home.

Be that as it may, a LAN can be associated with other local area networks paying little mind to separate, since it utilizes different systems, for example, radio information transmission and others. This is called WAN or Wide Area Network, as we can see further down in this article.

Without a doubt, the main trait of the LAN is that it permits the interconnection of different hubs or individual PCs, to get to the information and assets they have, that is, we can utilize printers, stockpiling units and different gadgets in any event, when not are actually associated with our PC.

Another attribute of LANs is that they communicate information to one another at extremely rapid, anyway the distances at which they can do so is restricted, just as the quantity of hubs that can be associated with a solitary LAN.

- Network WAN (Wide Area Network)

Called Wide Area Network , or WAN (Wide Area Network) and is additionally known is essentially at least one LANs interconnected to cover a substantially more area, in some cases, even landmasses.

The networks WAN are generally utilized by huge organizations for their own utilization, while others are utilized by WAN ISP to give Internet administration to its clients . PCs associated through a Wide Area Network or WAN are by and large associated through open networks like the phone framework, anyway they can likewise utilize satellites and different systems.

- MAN Network (Metropolitan Area Network)

MAN or Metropolitan Area Network , whose interpretation into Spanish is Red de Area Metropolitana, is an information network explicitly intended to be utilized in areas of urban communities or towns. The main trademark, talking regarding geographic inclusion, is that Metropolitan Area Networks or MANs are bigger than local area networks or LANs , yet more modest in geographic extension than wide area networks (WANs).

MAN are portrayed by rapid associations utilizing fiber optic link or other computerized media, which permits it to have a much lower mistake rate and inertness than different networks furnished with different sorts of conductors. They are additionally entirely steady and impervious to radio-electric impedance.

This reality makes metropolitan area networks truly appropriate for interactive media traffic conditions, which permits, in addition to other things, to carry out observation frameworks through camcorders with a massive expense/advantage proportion.

- WLAN Network (Wireless Local Network)

A Wireless Local Area Network, also called WLAN , is fundamentally an information move and correspondences framework which doesn't need that the PCs that create it must be wired together, since all information traffic between them is performed by means of radio waves wlan router.

In spite of the fact that they are less secure than their wired partner, they offer a wide assortment of benefits, and that is the reason their execution fills step by step on the whole areas.

Notwithstanding, the most exceptional quality of wireless networks is the reserve funds in the laying of links for the interconnection of the PCs and gadgets that create it, since it doesn't need any link for its interconnection, an incredible benefit for the home , the workplace and SMEs.

WAN, WLAN, MAN and LAN: what is each and how are they different

There are many terms related to networks and the Internet that we can see. When we navigate different devices and protocols come into play that are necessary. Some of them may raise questions for users. There are terms like WAN, WLAN, MAN or LAN that are sometimes confused. We are going to talk about this in this article. We are going to explain what each of these three terms is and see their differences.

WAN, WLAN, MAN AND LAN

We are going to talk about what each of these network protocols is. We are going to explain what is WAN, WLAN, MAN and LAN. In this way, users will know how to differentiate when they see these terms.

What does WAN mean

Let's start to explain what WAN means . We could say that it is a network of networks. In other words, it is a large network to which different local networks are connected. Of course, it must be borne in mind that all the devices that compose it do not have to be physically in the same place.

WANs are typically built by organizations and companies to have a private network. Keep in mind that nowadays they are not as necessary as before, since the Internet speed is considerably higher wlan properties.

A WAN network could cover a distance of even thousands of kilometers. Hence what we mentioned earlier that the devices did not have to be physically in one place.

They allow LAN networks to be connected with other types of networks. In this way we can connect with teams that are in another part of the world.

Today all routers have a WAN port . It is the port through which our router obtains the services of the Internet operator that we have. The speed of that port will depend on the technology we use (ADSL or VDSL, for example).

What does MAN mean

We have something similar to WAN but using less capacity in terms of distance. It comes from the acronym in English Metropolitan Area Network . It offers great coverage, but less than WAN. They use different technological standards that allow them to cover a greater distance.

It can be both wireless and wired . In the case of using the wireless option it is called WMAN.

This can be used for example to link the networks of several buildings, a university campus or even a city. It does not reach the thousands of kilometers that we mentioned earlier.

What does WLAN mean

By WLAN we mean a wireless local area network . Basically it is to connect between devices that are within a radius.

To connect a device in WLAN we will need to have a compatible network card, as well as a computer that provides the connection, such as a router. Today practically all mobiles can connect to this type of network. It is what we know as having Wi-Fi compatibility .

We can configure a WLAN network so that two or more devices are connected. They have to be compatible and have a network card, as we have mentioned. They can work in both the 2.4 GHz and 5 GHz bands. Depending on the equipment, it can work in a single band, in double band or even in three simultaneous bands.

enable wlan

As information networks fill in size, they increment their traffic and number of hubs, which is the reason it is important to apply the essential rules that each organized organization should agree with to be worked proficiently:

One of the issues that organizations don't typically give extraordinary consideration to is the inner correspondences organization. Dividing and measuring the neighborhood organization can help tackle a large number of the issues that happen at the correspondences level. For this, it is fundamental to distinguish if the organization is filling in number of associated clients and hosts, as a result there are challenges like low execution, gradualness, instability and data spillage.

What's the significance here to deal with the organization?

Today, little and medium-sized organizations, similar to enormous organizations, depend like never before on their IT framework. We can say unafraid that the information network is the foundation of the business. Steady accessibility, without interferences, and ideal organization execution, have become basic components for the achievement of the organization. The littlest issue with the organization can have decimating impacts and cause lost deals, disappointed clients, addressed believability on the lookout and lost profitability enable wlan.

What is edge security?

It is a first line of guard, ensuring significant business data since high velocity Internet associations are consistently dynamic, it tends to be powerless against security dangers. Infections, spyware, Internet assaults, email hacks, and other security concerns are the genuine threats. A hearty stage for access control and assurance of PC administrations ensures right utilization of the framework and ensures the respectability and privacy of the data.

Wi-Fi and the difference between speed over LAN and over Wi-Fi

Today we are accustomed to seeing WiFi networks in each home , once in a while we even utilize the WiFi association notwithstanding being a couple of meters from the switch. Truth be told, we've arrived at a point where utilizing an organization link may appear to be a simple arrangement wlan range.

Nonetheless, we will perceive any reason why it is prudent to utilize a link at whatever point we can and leave the remote association for the events when we can't utilize a link. A couple of years prior our Internet associations weren't however quick as they may be currently , so when it came to perusing there was no large contrast between utilizing a WiFi connect and an ethernet one. In any case, today we have fiber optic associations, with speeds tantamount to those of our nearby organizations. In these conditions we should pick well what kind of connection we use since our experience when utilizing our association may rely upon this choice .

A WiFi interface makes us lose a normal of 60% of the transfer speed of our Internet association. This misfortune is created by factors straightforwardly identified with the utilization of a common medium, the air:

Wifi

Obstructions: Since remote correspondences are completed in a free-use recurrence range, we can discover numerous frameworks that utilization similar frequencies as our WiFi organization. For instance: remote consoles and mice, microwaves, cameras, cordless telephones, and so on The 802.11 a/b/g/n conventions are set up to withstand this sort of obstruction, however in return for loss of execution.

Distance: The further we get from our passage, the more troublesome it will be for them to look after correspondence, so they should send all the more gradually to guarantee that correspondence is completed effectively.

Snags: Related to the distance since, by and large, the further we go from the switch, the more hindrances are mediated between the two gadgets, with the goal that the sign needs to cross them. Contingent upon the material with which they are made, we will lose pretty much force, thusly the speed should be diminished to decrease the likelihood of mistake.

Perusing

Shared station: Currently in link networks a common medium isn't utilized, every PC has its own connection, in any case, in remote correspondences all PCs utilize a similar medium, so the speed must be appropriated among all the that are associated with the organization.

Half-duplex: But not exclusively is the speed dispersed among every one of the PCs, it additionally relies upon whether we need to send or get data. In WiFi networks there is no upstream and downstream station, as in link organizations, so the gear can just utilize the channel to send or to get, yet never for both simultaneously .

To peruse, see email and check our informal organizations we won't see a distinction between a WiFi interface and a link interface, yet on the off chance that we play out a substantial download we will perceive how we can't utilize all the transfer speed of the association, and we may even figure that We don't have the speed that the administrator guaranteed us. Thus, on the off chance that we need to play out a speed test or download content from the Internet, it would be strongly prescribed to utilize a gadget associated by link to the switch, so we can take advantage of our association .

wireless lan card

WLAN is an acronym of the English language which refers to Wireless Local Area Network , an expression that can be translated as Local Area Network Wireless . As the name indicates, a WLAN is a local type network whose computers do not need to be linked by cables to connect.

WLAN is a specific type of LAN : a computer network made up of units located in a small geographic space. While computers (computers) that are part of a LAN are connected to each other or to a wired router, in a WLAN the connection is made using radio frequency waves .

As they are wireless networks , WLANs often allow users to have wide mobility, since they do not depend on cables or physical elements to stay on the network. The absence of cables also contributes to maintaining order or organization in the office or environment in question.

An example of WLAN is the wireless network that is installed in a home using WiFi technology . Suppose there is a computer in a bedroom, another computer in the dining room, and a third laptop. All three computers have wireless network cards and are interconnected through a wireless access point (a device known as WAP for its acronym in English). In this way, the parent who uses the computer in the dining room can send a photograph to his son, who uses the computer in the bedroom. At the same time, the two of you can share files with whoever uses the laptop.

There are two main problems or weaknesses, let's put it like this, that a WLAN has:

-Security. It is considered that this is much more vulnerable than other networks, so it is necessary to take all possible measures in order to prevent anyone from accessing it. Hence, for example, what is chosen is encryption and the use of different keys and algorithms.

-Speed. In the same way, there is still much better for WLANs in this regard. And it is considered that, at present, it has not yet managed to reach the speed that they do offer and have other types of local networks.

Faced with these setbacks or weaknesses of the WLAN, we can highlight its most notable advantages, some of which you have already been able to intuit to a certain extent:

-In companies it gives the possibility that any employee can obtain information from any part of it from your position and immediately. One circumstance that, without a doubt, contributes both to making your work easier and to significantly improving your productivity wireless lan card.

-Although it may involve a higher cost at first in many cases, in the long run it is a much more profitable investment.

-The WLAN is installed really quickly and easily, so that you will be able to make use of it immediately.

-Precisely also the changes that have to be made are very easy to undertake.

The two components of WiFi

In a WiFi association we have a remote connector in a PC - or other gadget - that deciphers the information as a radio sign and, through a recieving wire, communicates it 'over the air' . What's more, a switch, additionally remote, which is liable for accepting the sign and disentangling it. What's more, whenever this is done, by an actual association, by link, through Ethernet, it sends the data through the Internet to different workers what does wlan mean.

Clearly, this entire interaction happens precisely something similar, yet in turn around, when the 'customer' needs to get data from the Internet. The remote switch gets information that it converts into a radio sign and sends it to the remote connector. This can occur in 2.4 or 5 GHz, as we referenced previously, and on the 802.11 a/b/g/n/ac norms. There is in reverse similarity between principles of connectors and passages, and in the most recent details it very well may be communicated all the while in two groups for a higher speed in information move.

Norms ensured by the Wi-Fi Alliance

There are different kinds of WiFi dependent on an IEE 802.11 norm. that the actual Alliance ensures and that comprises of a progression of remote principles made by the Institute of Engineers and Electronics (IEEE). Among the main norms, it merits featuring:

IEE 802.11

As it were, it is the base norm for remote organization correspondences. It doesn't return to the furthest limit of the 90s and it permitted to move information at 1Mbps.

IEE 802.11a

The principal modification of the 802.11 standard was brought into the world back in 1999 and works on the 5 GHz recurrence band, with a greatest speed of 54 Mbps, in spite of the issue of unnecessary lessening noticeable all around because of the band noticeable all around. working, so it was important to contemplate extension to new recurrence groups.

IEE 802.11b

The 802.11b amendment before long started to appreciate extraordinary general acknowledgment on the grounds that working in the 2.4 GHz band diminished lessening taking out numerous impedances and improving the nature of the Wi-Fi signal. The transmission speed it offered was set up at a hypothetical 11 Mbit/second , yet its fundamental disadvantage was that indoor inclusion was restricted to a sweep of 50 meters.

IEEE 802.11g

Without leaving the 2.4 GHz transfer speed, the Wi-Fi g affirmed in 2003 approached the hypothetical greatest transmission speed of 54 Mbit/sec, the standard a yet in addition improved the indoor and outside inclusion offered by the b standard , which caused the promotion of groups that carried out it around the planet.

IEE 802.11n

Otherwise called WiFi 4. Without a doubt one of the incredible defining moments in remote associations, because of the execution of MIMO networks in the Wi-Fi standard, since albeit these radio wires were at that point present in 802.11g hardware, they started here to standardize on account of the benefits of this innovation. As well as being viable with the past guidelines, with Wi-Fi 802.11n exchange rates of somewhere in the range of 150 and 600 Mbps are covered, ensuring stable association paces of 300 Mbps in the last case.

Then again. the MIMO innovation utilizes numerous reception apparatuses introduced on the switch for sending and accepting information all the while. Applied to this norm, it assists with accomplishing inclusion of up to 120 meters inside and 300 meters outside.

IEEE 802.11ac

Otherwise called WiFi 5 or Gigabit WiFi, the new WiGig standard carried extraordinary rates to remote associations and verification of this is the advancement accomplished with Wi-Fi 802.11ac . On account of beamforming innovation to center radio signals, the scope of these remote organizations is prevalent even notwithstanding working in the 5 GHz band and at a lot higher velocities because of different reception apparatuses - up to a limit of 4-. For this situation, the hypothetical speed is repaired at to 1,300 Mbps .

IEEE 802.11ah

This survey is likewise known under the name of HaLow , This audit known as "HaLow" has been the last to show up and makes it willing to propose a genuine option in contrast to Bluetooth to misuse the Internet of Things area and channel associations of associated gadgets in the home tomorrow. For this situation we are discussing a 900 MHz transmission capacity , which is the reason it offers a more noteworthy reach than networks that work on 2.4 GHz, just as assisting with easing up this band by restricting the association traffic of associated home gadgets.

IEE 802.11ax

Otherwise called WiFi 6 and intended to work in the 2.4 and 5 GHz spectra. As well as utilizing MIMO and MU-MIMO, this new standard acquaints OFDMA with improve in general unearthly proficiency and convey better. It is viable with the above conventions and offers a hypothetical most extreme speed of 10 Gbps.
